physics midterm review

Front

What is the Formula for speed?

Back

s=d/t

Front

How are acceleration and velocity related?

Back

Acceleration is the rate of change of velocity in time.

Front

Is a car stopping for a red light accelerating?

Back

Yes, because it's changing its velocity.

Front

What is the acceleration of a car that travels in a straight line at a constant speed of 100km/hr?

Back

0km/hr

Front

What is the equation for horizontal projectile motion?

Back

v=d/t

Front

How are mass and inertia related?

Back

Directly proportional

Front

What is the difference between mass and weight?

Back

Mass = matter; Weight = gravity on the mass

Front

How does mass affect acceleration?

Back

When one grows, the other shrinks, inversely.

Front

If an object is not accelerating, does that mean there are no forces acting on it?

Back

No, gravity will be acting on it.

Front

What is momentum?

Back

Movement, magnitude and direction
