Kinematics
A cart moving at a constant speed along a frictionless track collides with a stationary cart of equal mass; how do their speeds compare after an elastic collision?
The first cart reverses direction, while the second remains stationary.
Both carts move together at half the initial speed.
Both carts remain at rest after colliding.
The initial moving cart stops, and the second cart moves at the initial speed.
What happens to the acceleration of an object if the net external force applied to it is doubled while its mass remains unchanged?
The acceleration quadruples
The acceleration remains unchanged
The acceleration doubles
The acceleration is halved
What force is required to keep a 5 kg object moving at a constant velocity of 10 m/s?

0 N
50 N
10 N
If a car traveling in a straight line triples its velocity over a certain time interval, by what factor does the kinetic energy of the car change within that same time interval?
The kinetic energy doubles.
The kinetic energy remains constant.
The kinetic energy increases by a factor of six.
The kinetic energy increases by a factor of nine.
Given two projectiles launched at different angles but with identical initial speeds, how does their time of flight compare if air resistance is negligible and they land at the same height they are launched from?
Time of flight increases as launch angle approaches vertical.
Time of flight is identical for both projectiles.
Time of flight depends on launch angle but not initial speed.
Time of flight decreases as launch angle approaches horizontal.
To investigate how non-inertial reference frames could affect projectile trajectories contrary to classical mechanics predictions, what kind of experiment could be designed?
Repeating Galileo’s ramp experiments on a moving train and comparing results with stationary setups.
Dropping objects off a spinning disc and measuring radial displacement upon landing relative to traditional expectations.
Launching missiles at high latitudes where Earth's rotation speed differs significantly, observing deflections against calculated values.
Firing projectiles within a rotating space station and analyzing trajectory alterations compared to non-rotating environments.
If two particles undergo an oblique elastic collision and one particle initially at rest ends up moving at an angle with respect to its original position, what was the initial speed ratio between them assuming they have equal masses?

What motion property is directly related to an object's velocity?
Moment Inertia
Acceleration
Displacement
Linear Momentum.
A particle starts at rest and accelerates along a straight line under variable acceleration , where is a positive constant and ; how does changing influence the particle's position after some fixed time ?
Changing n does not have any effect on the particle's position after time T.
The value of n affects the shape of the velocity function and therefore the position function.
The position of the particle after time T is directly proportional to the value of n.
A satellite orbits Earth in circular orbit with orbital velocity , calculate the change in its kinetic energy when it radially moves from orbit radius to where using only universal gravitation constants and masses involved.
