Physics Velocity and Motion Quiz

Velocity at a specific point in time.

The slope of a graph; used to determine the rate of change or velocity.

Velocity is calculated as the gradient (slope) of the displacement-time graph.

A line that touches a curve at a single point, used to find the instantaneous rate of change at that point.

A graph showing the change in displacement over time.

A graph showing how velocity changes over time.

Find instantaneous velocity by drawing a tangent to the displacement-time curve at the desired time and calculating its gradient(slope).

Calculate average velocity by dividing total displacement by total time

The vertical velocity of a projectile is zero at its highest point.

Use the equation s = ut + ½at² with downwards as the negative direction.

Calculate the time it takes for a projectile to reach its highest point by setting the final vertical velocity to zero in the equation.

Calculate horizontal distance using s = ut.

Calculate the vertical displacement using the equation v² = u² + 2as, where v=final velocity, u= initial velocity, and s=vertical displacement.

Projectile horizontal velocity remains constant throughout its flight (assuming no air resistance).

The time it takes for a projectile to complete its trajectory.

Find horizontal displacement by multiplying the horizontal velocity (constant) and the time of flight.

An object thrown with an initial horizontal velocity and then subject to gravity.

The time a projectile takes to reach the ground is determined solely by its initial vertical velocity and the acceleration due to gravity.

The horizontal velocity of a projectile remains constant throughout its flight, neglecting air resistance.

The vertical velocity of a projectile changes due to the constant acceleration of gravity.

The initial vertical velocity of a horizontally launched projectile is zero.

The path a projectile takes through the air, usually a parabolic curve.

To find the final velocity of a projectile, you need to calculate the components of its horizontal and vertical velocities at the point of impact and combine them using vector addition.

The angle at which a projectile hits the ground. It is determined by the ratio of the horizontal and vertical components of its velocity.

The equation to calculate velocity is v = u + at, where v is final velocity, u is initial velocity, a is acceleration, and t is time.

The equation to calculate displacement is s = ut + ½at², where s is displacement, u is initial velocity, a is acceleration, and t is time.

'u' represents the initial velocity of an object, meaning the velocity at the start of its motion.

Objects launched horizontally or dropped from the same height will hit the ground at the same time. Their vertical component of velocity is the same at all times.

'a' represents the acceleration of an object, meaning the rate at which its velocity changes over time.

't' represents the time taken for an object's motion, meaning the duration of the movement.

To find the speed of a projectile, use the Pythagorean theorem with its horizontal and vertical velocity components.

's' represents the displacement of an object, meaning the change in its position from its starting point.

When an object comes to a stop, its final velocity (v) is 0. We can use the equation v² = u² + 2as to calculate the initial velocity (u) or displacement (s).

Use the equation s = ut + ½at² to calculate vertical displacement, where 's' is displacement, 'u' is initial velocity, 't' is time and 'a' is acceleration due to gravity (g).

You use the equation v² = u² + 2as, where v is final velocity (0 when it reaches its highest point), u is initial velocity, a is acceleration due to gravity (-9.8 m/s²), and 's' is the displacement (height).

The resultant velocity includes both magnitude (speed) and direction (angle).

The movement of an object launched into the air, affected by gravity.

The constant speed of a projectile in the horizontal direction, unaffected by gravity.

The speed of a projectile in the vertical direction, affected by gravity.

The time it takes for a projectile to reach the ground after being launched.

The total distance a projectile travels horizontally before hitting the ground.

The angle at which a projectile is launched relative to the horizontal.

The starting speed and direction of a projectile.
