What is the kinematic relationship for velocity in terms of initial velocity, acceleration, and time?

v = u + at

v = u + 1/2 at^2

v = u^2 + 2as

v = u + s

Answer explanation

The correct kinematic relationship for velocity in terms of initial velocity, acceleration, and time is v = u + at.

How can the gradient of a velocity-time graph at a given time be interpreted?

It represents the instantaneous velocity.

It represents the instantaneous acceleration.

It represents the total displacement.

It represents the change in displacement over time.

Answer explanation

The gradient of a velocity-time graph at a given time represents the instantaneous acceleration.

What does the area under a velocity-time graph represent?

The change in acceleration.

The instantaneous velocity.

The total displacement.

The average velocity.

Answer explanation

The area under a velocity-time graph represents the total displacement, not the change in acceleration, instantaneous velocity, or average velocity.

What is torque commonly referred to as?

The linear effect of a force

The turning effect of a force

The stopping effect of a force

The accelerating effect of a force

Answer explanation

Torque is commonly referred to as the turning effect of a force, causing an object to rotate around an axis.

What does the torque T = Fr represent?

Torque equals force times radius

Torque equals force divided by radius

Torque equals force plus radius

Torque equals force minus radius

Answer explanation

Torque equals force times radius because torque is the product of the force applied and the distance from the axis of rotation (radius).

What happens when an unbalanced torque acts on an object?

It produces a linear acceleration

It produces an angular deceleration

It produces an angular acceleration

It has no effect on the object

Answer explanation

When an unbalanced torque acts on an object, it produces an angular acceleration, causing the object to rotate faster or slower depending on the direction of the torque.

What is the moment of inertia a measure of in an object?

Its resistance to linear acceleration

Its resistance to angular deceleration

Its resistance to angular acceleration

Its resistance to velocity changes

Answer explanation

The moment of inertia is a measure of an object's resistance to angular acceleration, not linear acceleration, angular deceleration, or velocity changes.
